Critique of “Elastic thickness of the Venus lithosphere estimated from topography and gravity” by A. Cazenave and K. Dominh

Abstract

Cazenave and Dominh compare the topography in a portion of the rolling plains province of Venus with a measure of the corresponding gravity perturbations, the residual acceleration of the Pioneer Venus Orbiter. They ignore substantial geometric factors and make unsubstantiated geophysical assumptions to draw conclusions which we consider logically invalid and numerically implausible.
